Dermatoglyphics as biological markers of sports performance

Abstract

Influence of genetic potential to improve physical aptitude and manifestation of physical effort has gained space in physical education and sport. Dermatoglyphics is still scarcely explored among biological indicators of performance, although they are becoming more and more known. They consist of dermopapillary palmar-digital impressions, for instance, of the set of dermal papillae of fingers, palms, soles, genetically established and changeless over the life. Preferential frequency distribuitions are observed in digital patterns (arches, loops, whorls) according to different modalities, as well as varied grade on total ridge count. This trended to be lower in persons involved in cyclic activities in comparison with competitors of strength modalities. Ab line count lessens in progression with sport level, elite athletics show atd angles lower than population values, as well as ulnar and combined indexes. Lastly, multivariate analysis to investigate the relations between dermatoglyphics and sport performance is considered. Thus, it was accomplished the aim of this review of doing a critical analysis of articles referents to dermatoglyphics from frequency distribution of its variables, from the relationship of this variables and sports performance and talent orientation.
